Yes, but not what she expected

I stepped on the first step of the stairs waiting for Lucy to enter the laundry room. She left the door open as expected and I watched her bare bottom approach the washing machine where she put her clothes and mine in without hesitating. Sometimes I caught her just holding the clothes in her hands while getting teary eyed but I’ve never seen her try to put any on no matter how tempted she must be.

I slowly walked towards the laundry room on bare feet making sure to not alert her to my presence. She backed away towards the dryer which meant I couldn’t see her. I sped up to make sure she wasn’t trying to break any of my commands. I got to the doorway expecting to catch her trying to sneak on a pair of panties or something similar when I heard the dryer turn on despite the fact there should be nothing coming out of the washer to put in it. Then I heard something else, something unexpected. A moan.

I slowly poked my head in and saw my sister sitting on her bare-ass on top of the dryer, rubbing herself. She moaned again when I realized her eyes were closed. She took her left nipple in her hand while she rubbed harder with her right. I was watching her, who looked exactly like me, masturbate. I wasn’t sure if I should interrupt but I knew it would be a lot more interesting if I did.

“Ahem.” I said loudly.

She opened her eyes and looked absolutely shocked and humiliated. She pulled her hand back and started crying.

“I’m sorry... I’m sorry... please don’t tell mom!” She pleaded.

I tried to not look intimidating but given my authority over her it might be impossible for her not to feel that I was.

“There’s no rule against you masturbating.” I said as she pulled her knees up to her chest and moaned from the vibrations of dryer.

“Don’t... tell mom. Please.”

I walked up to her and helped her down from the dryer. She fell into me a little and her nude form rubbed against me. I ignored her request for the moment and asked her an embarrassing question instead.

“Are you getting off on this? Remember we agreed to total honesty.”

She shook her head rapidly obviously feeling very ****.

“Then explain yourself.”

She swallowed deeply while pulling on her fingers.

“I... I just got too close... during your inspection....”

she opened her eyes wide in panic as she must have felt she had challenged my authority in some way. She spoke so fast it was almost hard to follow as she tried to dig herself out of the hole she thought she had dug herself into.

“... I mean you have every right to inspect however you see fit! Just... it was too much... I mean for me! You still can do it how you want.. I was just so close to... cumming... and I couldn’t help myself.... Please... please... don’t tell mom.”

She waited for me to respond but I didn’t.

“Please... this is so horrible... I just know she’ll make it worse...”

Her eyes watered.

“Lacy, please... There’s no way she can escalate my punishment any further without making it public knowledge. I really... really can’t handle that.”

I finally spoke. I ignored most of what she said as I wasn’t quite sure how I wanted to play this.

“So you’re not turned on being kept naked, cavity searched, and controlled, it was just a physical response to my inspection?”

She calmed down a little.

“Yes, that’s it. I really hate this but that was just too much... I mean for me. You can do it if that’s what you think is best... I just need to get used to it. You’ve never spent that long or done that much before but I promise to cooperate. Just don’t tell mom, I did this. I know she’ll make it worse.”

I’ve never seen her beg like this before; she really was scared of this getting any worse for her. I hugged her and rubbed her bare back stopping at the tops of her ass cheeks and she whimpered but didn’t protest.

“Mom isn’t trying to hurt you she just wants you to learn your place. That’s it.”

She pulled on her fingers, spreading the juices between both hands, while nodding trying to think of the right words as tears formed in her eyes. I felt bad so I finally said something she might want to hear.

“Okay, I’ll consider not telling mom but you gotta talk to me. You’ve really shut me out since this started.”

She backed out of my hug and rubbed her bare right foot against the back of her left calf while looking down and pulling her fingers.

“What... what did you expect? You... for a lack of a better word... own me. I haven’t worn clothes in the house for two months and you get to... order me around... and spank me... touch me anywhere and.... be inside me...”

She whispered softly while taking panicked breaths afraid she might say the wrong thing.

When I took a moment to respond she sobbed afraid of consequences for speaking her mind, I assume. She wasn’t sure to what to do with her own hands covered in her juices that matched her thickly coated thighs.

“I do it for your own good, Lucy. You gotta learn to behave. I’m scared of you getting in more trouble. Now I’m a little scared because it seems like you might actually enjoy the trouble you’ve already gotten yourself into.”

She frowned, humiliated. I walked closer and she backed away. I stepped closer again and she continued to back away so I kept going until her ass was pressed against the dryer. It didn’t take long until she moaned again as the vibrations went through her. I stood in front of her so she couldn’t step away from it and moaned again and again.

“This is what I’m talking about. Has this all been an act? You really like being treated like this?”

I knew it wasn’t an act but I was getting off on this and I couldn’t help myself watching my naked twin squirm and moan.

“No...ooo. This is... the fi-irst... time... I-I prom-mise.”

I stepped closer again and before I pressed into her she pushed herself back up onto the dryer. she must have felt she had nowhere else to go but watching my mirror image moan and pant naked on the dryer was pushing me closer to breaking the self control I’d shown this far. Feeling her second hand humiliation and knowing I caused it was the most powerful feeling I’ve ever felt. I wanted more.

“If this is arousing you, then maybe we need to talk to mom. We might need to think of something a little tougher for you.”

She moaned again and shook as she rocked on her bottom against the dryer. I watched her spread legs become more thickly covered as she tried to hold herself together.

“No...ooo...” she mewled.

I couldn’t let this go much further, I knew I went a little too far with what I just said but she was clearly very close to cumming. I reached up to her and grabbed her shoulder like I was trying to help her off but I pushed her a little as she tried to hop down from the dryer knowing she was **** to not cum in front of me. As she hopped off she began to fall, between my small nudge and her sweaty bare feet she slipped on the tile and she fell forward, exactly as I planned. I ‘accidentally’ caught her by the crotch, and as I gripped her and my hand rubbed over her vulva slightly, she came.

She moaned loudly as I felt juices evacuate out of her and she spasmed in my arms. She couldn’t meet my eyes as she started to breath heavily in panic, whether due to the humiliation, the fact I made her cum, the fact she came in my presence or the fear that this was all the proof I needed that she got off on this, I couldn’t say.

After a minute she just panted lightly and I released her crotch. I needed to get a hold of myself, I knew I was only doing this because I imagined her as myself and it was just so hot being both humiliated and humiliator at the same time but my sister is a real person with real feelings and I needed to remind myself of that.

“Are you okay?” I asked her.

“I...I... I just came.” She said mortified though obviously I knew.

After coming down she breathed a little easier and stood on her own. I released her and we both stepped back from each other.

“Thank you for your honesty. Did it feel good?” I asked her.

She took a deep breath trying to center herself before responding.

“Physically, well of course it kinda felt nice but, it’s very humiliating to cum in front of you, on you, while living as your naked prisoner.” She said gazing at the floor and her bare feet she groaned in frustration and the fear she had said too much.

“It’s okay, I’m not judging you. You’re not my prisoner, you’re my sister, I’m just in charge of you until you learn your lesson. You’re dealing with consequences of your own actions, I wish you hadn’t made so many mistakes.”

She nodded quickly and nervously afraid of me. I was trying to appear sympathetic and to hide my enjoyment of the whole situation.

“Please... please don’t tell mom.”

I wasn’t sure whether to tell my mom but I knew I could save it for later and her vulnerability was starting to get to me.

“You promise this is the first time?” I asked.

“Yes, yes, I promise! I haven’t felt like anything sexual since this started you just... you just did what you felt you had to and it got me a little worked up...”

She was trying to be respectful while explaining herself.

“I won’t tell mom, but if I really start to think you’re enjoying this I may have to. If this never happens again then I won’t have to.”

She ran forward and hugged me and though she was covered in sweat and juices I hugged her back.

“Thank you, thank you so much. I promise I don’t enjoy this.”

We embraced for a while her naked breasts pushed into me. Finally she let go.

“Okay, now meet me in my room with your hairbrush.”

I expected her to get upset that she was still in for a spanking but I guess she was just so happy that I wasn’t going to tell my mom she actually smiled and went to go get her hairbrush.
